In 2014, we had a linear ballista-style ball launcher that used really fat latex tubing. We were running into concerns about the wear and tear on the tubing because it only wrapped around two 1/4 bolts, and there was probably upwards of 150+ pounds of tension in the launcher when retracted. So yes, lots of pressure on a little surface.

It was evident that lubricant was necessary, but as the material was latex, we had to opt for water-based lubricant since oil-based lubricants degrade latex. Well, the only water-based lubricants available near the regional were in the form of personal lubricants at the nearby drug stores and supermarkets.

In our pit for the rest of the event, we had a tube of Astroglide covered with red duct taped and labeled "Secret Sauce." We applied a fresh coat to the latex tubing before every match.

Not sure if it's the kind of "ghetto" you're looking for, but it's certainly an unexpected fix to a problem. Worked like a charm, though.
